MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented May 26, 1914.

Application filed November 25, 1913. Serial No. 802,926.

To all whom it may concern Be it known that I, ADAM J. ILLIG, a citizen of the United States, and a resident of Rozellville, in the county of Marathon and State of \Visconsin, have invented a new and Improved Music-Leaf Turner, of which the following is a full, clear, and exact description.

My invention relates to a music leaf turner employing swinging members to turn the leaves, and particularly to an apparatus in which the leafturning elements are actuated by manually-controlled, motor-driven elements.

The invention will be particularly explained in the specific description following.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of a music leaf-turner embodying my invention; Fig 2 is a side view on a reduced scale, indicatingthe position of the device on a musical instrument; Fig. 3 is a fragmentary sectional plan View, the view being given to show the drive means; Fig. 4 is a detail vertical section on line 1-4 of Fig. 3; Fig. 5 is a fragmentary perspective view given to show the means for engaging the music leaves with the carrier arms; Figs. 6, 7 and 8 are sectional plan views taken respectively on the lines (3-43, 7-7 and 88 of Fig. 9; and Fig. 9 is a partly sectional rear elevation of the music leaf turner, the motor shown in Fig. 3 being omitted.

In constructing the illustrated practical embodiment of the invention, any suitable case 10 is provided to contain the operative means, and constructed of a character to be supported on a musical instrument B, or the like, indicated by dotted lines in Fig. -l, the case being provided with suitable rests for the music sheets A, there being in the example shown a. central rest 11 and auxiliary side rests 11. To turn the leaves a series of rock shafts are provided in any desired number, there being shown by way of example, four of such rock shafts. shafts are suitably secured lower arms 13 and upper arms 1?), said arms being adapted to move in horizontal slots 11 and 14 respectively in the and other elements, proper frame mcu'ibers front 15 of the case 10. To 1 provide suitable bearings for the rock shafts I with a spur pinion 38 on the shaft 39 of an ()n the rock:

ti 1 i are formed within the case 10. I have shown in the present instance, an upper partition 1G, a lower partition 16 a pair of spaced front and back rails 16", 16, below the partition 16, and front and back rails 16f, 16*, below the first pair of rails, there being cross bars 16 joining the rails of the first pair, and similar cross bars 16 joining the rails of the lower pair.

In order to actuate the rock shafts 12 to swing the arms 13 from right to left, or left to right, each shaft is provided with a sprocket pinion, the shafts being arranged alternately shorter and longer in order to accommodate the sprocket pinions in the smallest horizontal space; thus alternate shafts 12 are provided with sprocket pinions 17, the intervening shafts being continued below the pinions 17 and provided with pinions 17, as best shown in Fig. 9. Sprocket chains are provided to actuate the respective pinions, there being an upper pair of endless chains 18 for the upper sprocket pinions and a lower pair of endless chains 18 for the lower pinions. These chains extend around sprocket wheels, the upper chains 18 running respectively at one side of the case around wheels 19 and at the opposite side around sprocket wheels 19*, and the chains 18 similarly running at one side of the case around sprocket wheels 19*, and at the other side around sprocket wheels 19. The respective wheels at one side are mounted on shafts 20, 20 and at the other side are mounted on shafts 21. The shafts 20, 520, are driven from a drive shaft 22, the shaft 20 being directly driven by a pinion 23 on the drive shaft 22 meshing with a pinion 24 on the shaft 20, while the shaft 20 is driven indirectly from the pinion 23 by an intermediate pinion 26 meshing with a pinion 25 on said shaft 20, so that the shafts 20, 20 will thus be driven in the same direction.

Any suitable motor-driven gear may be employed to actuate the drive shaft i The means illustrated in Figs. 3, 4t and 9, include a worm wheel 27 on the drive shaft 22, said wheel meshing with a worm 28 on a shaft 29 that carries a clutch element 30, there being a co-acting clutch element 31 controlled by a clutch lever 32 mounted on a separate axially alined shaft 33. The shaft 33 is provided with a miter gear 34 meshing with a miter pinion 35, on the shaft 36 of which is a spur pinion 37, which in turn meshes electric or other motor 40. A retractile spring 41 connected with the clutch lever 32 tends to maintain the clutch elements 30, 31, out of engagement, and to throw the clutches into engagement a cord or other flexible element 42 extends from the lever 32 to any suitable treadle devices 13 (see Fig. 2). The arrangement is such that when the clutches are thrown into engagement by the player the shafts 20 will cause the chains of each pair to travel in the same direction. The chains, as will be clear from Figs. 6 and 7, are arranged so that adjacent runs of the chains of a pair will run in the same direction, and the pinions 17, 17 are disposed between the said adjacent runs. The shafts 12 are mounted for bodily transverse movement so as to be shifted to bring the pinions 17, 17, into engagement with either chain of a pair, one chain thus serving to turn the pinions in one direction while the adjacent runs of the adjacent chains will turn the pinions in the opposite direction.

The various frame members through which the shafts 12 pass are suitably slotted for the transverse movement of the shafts, there being provided in addition to the partitions 16, 16, plates 44 carried by the pairs of rails 16 16 and 16 16 said plates are provided with slots 4.), the partition 16 being formed with alined slots 15. For throwing the shafts and pinions, connection is made between the shafts and a series of push buttons 46, 16, mounted in pairs on the opposite arms of levers 47, which are fulcrumed intermediate their ends, as at 48, and provided with springs 49 normally tending to maintain the levers in such positions that the pinions 17, 17 will be out of engagement with the chains, an inward pressure on the push buttons 16, 46* of a pair serving to throw the pinions into mesh with either chain of the pair. The connection be tween the push buttons 46* and the shafts may be by means of yokes 50 rigid with the push buttons and embracing the said shafts.

In practice, all the sheets A of music being assembled at the right, the shaft 12 carrying the arms 13, 13 for the first leaf may be turned to swing the sheet to the left by pressing in the appropriate push button 46 which will carry the sprocket pinion associated with the particular shaft into engagement with the rear chain of a pair, and upon release of the push button, the spring 49 associated with that particular push button will restore the pinion and its shaft to the neutral position between the chains. The sheets having been all turned to the left the several arms may be restored to the position at the right by pressing the push buttons 16 associated with the opposite ends of the levers. To afford support for the chains at different points, friction rollers 51, 52, may be provided on transverse rods 53.

The engagement between the leaves of music and the arms 1; 13, is preferably effected by a pair of wires 13 connecting each arm of a pair, the said wires being adapted to receive between them the ends of a leaf A. Desirably the wires are joined to a helical spring 13 connected with either the upper or lower arm, or both, to maintain tension on the wires.

The described construction affords a practical means for carrying my invention into effect, and I would state in conclusion that I do not limit myself strictly to the meehanical details herein illustrated, since manifestly the same can be considerably varied without departure from the spirit of my invention.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent:
